TECHNICAL FIELD OF THE INVENTION

The present invention relates to a kitchen air-conditioning system.

BACKGROUND OF THE INVENTION

As a main place for people to cook, the kitchen air environment directly affects the mood of the cook. Especially in summer, the sultry kitchen environment brings great discomfort to the cook. Accordingly, various kitchen air-conditioners have been proposed to cool the kitchen.

There is no significant difference between the existing kitchen air-conditioners and common air conditioners. There are generally two forms of kitchen air-conditioners. One form is split kitchen air-conditioner. That is, the outdoor unit is located outdoors, the indoor unit is located indoors, and the indoor and outdoor units each have a motor fan. The connection of the indoor and outdoor units in the split kitchen air-conditioner is realized by pipelines. Such a connection requires the formation of a hole on the wall, which destroys the decoration. Since the outdoor unit is hung outdoors, the structure is not compact enough and it is less aesthetically pleasing. The other form is integrated kitchen air-conditioner. That is, a dual-axis motor or two motors may be used. The integrated kitchen air-conditioner usually comprises a portable air conditioner and a window unit. When the portable air conditioner is used, it needs to be manually connected to the heat dissipation hose, and then the hose needs to be placed outside the window, which is inconvenient to use. It is necessary to form a large square hole on the wall, into which the window unit is placed. When not in use, the window unit may be moved from the hole. Although the square hole may be blocked with other things, it is messy and it destroys the decoration.

Due to the limited space in the kitchen, the kitchen air conditioner should be not too large in size. Therefore, the heat dissipation of the kitchen air conditioner becomes a challenging problem. If the in-time heat dissipation of the kitchen air conditioner fails during its use, the energy efficiency of the air conditioner will be greatly reduced. However, the existing kitchen air conditioner and the range hood operate independently of each other, and they cannot be linked. The heat energy generated by the kitchen air conditioner cannot be exhausted to the outside through the fan of the range hood. Therefore, how to exhaust the heat energy generated by the kitchen air conditioner through the range hood becomes an urgent problem.
